This invention relates to hair slides which consist of two limbs between which hair can be gripped. In such slides it has already been proposed to provide one limb or bow with on closing of the slide are forced against the other limb or clasp bow or through openings in the latter so that the hair is gripped firmly between the limbs. It is found, however, that such constructions do not always lead to the desired result, and the object of the present invention is to provide an improved slide in which particularly firm gripping of the hair may take place.

According to the present invention two series of teeth are provided, one being fixed and the other being movably mounted in the slide so that with the slide closed the two series of teeth co-operate to grip the hair firmly but with the slide open they will re lease the hair.

In carrying the invention into effect it is preferred to make one limb of the slide boatshaped, this limb carrying the fixed teeth and containing a member carrying the movable teeth and mounted to slide within the boat-shaped limb. y In order that the invention may be clearly understood and readily carried into efiect,

some constructions in accordance therewith will now be described by way of example with reference to the accompanying drawings, in which Figure 1 shows one form of slide;

Figure 2 is a cross-section on the line II-II of Figure 1;

Figure 3 shows a modified form of slide;

Figure 3a shows diagrammatically the position of the teeth with the slide shown in Figure 3 open, while Figure 3b shows the position of the same teeth when the slide is closed.

Figure 4: is a cross-section on the line IV-IV of Figure 3, and

Figure 5 shows separately the clasp limb or bow of the slides of Figures 1 and 3.

Referring first to Figures 1 and 2, the slide comprises a boat-shaped limb 1 and a clasp limb or how 2 which is pivotally con- 5 nected to the limb 1 at 11. The fixed teeth is pivotally 515,066, and in Germany September 22, 1930.

{tare formed integral with and project upwards from the centre line of the boat-shaped limb 1. A member 3 carrying teeth 5 is-inserted within the trough of the boat-shaped member 1 and is formed with slots 6 through which the teeth 1 project. This member 3 can slide within the limb 1 within certain limits determined by the engagement of the teeth 4 with the ends of the slots 6 or by engagement with the ends of the member 3 with the ends of the limb. The member 3 is prevented from falling out of the boatshaped limb 1 by the bending over of the longitudinal edges of the limb as shown at 16 in Figure 2. The teeth 4 and 5 are so disposed that when the slide is open there is room for hair to be inserted between the teeth. In order to move the member 3 into a suitable position for this on the opening of the hair slide, the clasp bow or limb 2 is provided with a cam or like projection 10 which engages the end of the member 3 and moves it longitudinally within the boat-shaped limb 1 as the clasp bow 2 is swung about its pivot 11. On the closing of the clasp bow 2 an opening 17 which is made in it engages over a cam-like retaining hook 7 which is integral with the member 3, and the oo-operation of the side of the opening with the hook serves to push the member 3 towards the right as seen in Figure 1. This causes the teeth 5 to approach the stationary teeth 4 so that the hair is firmly gripped between the teeth. The member 3 can, of course, move towards the 5 right since the cam-like projection 10 moves toward the right as the clasp bow is closed. Referring now to the constructions shown in Figures 3 and 1, as before the clasp how 2 connected to the boat-shaped limb 1, but the fixed teeth 4 are fashioned from the side walls of the limb 1 so that the teeth 5 on the member 3 slide between the fixed teeth. The teeth are so disposed that when the clasp bow 2 is open the movable teeth accurately register with the fixed teeth 4 as shown in Figure 3a, but that when the clasp bow 2 is closedthe teeth 5 take up the position shownin Figure 3?).

A spring 8 is provided within the boat- 109 shaped limb 1 to bear against the end of the sliding member 3, this spring tending to force the member towards the right and thus to retain the latter in the desired end position. In order, however, to ensure the movement of the sliding member 3 to the right on the closing of the clasp bow 2, a ball shaped cam 9a is provided on the member 3 to co-operate with the opening 17 in the clasp how 2. The opening 17 is so shaped that when the clasp how 2 is pushed over the cam 9a the latter together with the whole slitiling member 3 must yield towards the ri t.

In the constructions shown in Figures 3 and 4 the sliding member 3 is prevented from falling out by turning over parts of the side walls between the teeth 4 as shown at 16 in Figure 4. An additional ball-shaped cam may be provided as shown at 9b to cooperate with the end of the main opening in the clasp bow to force the slidin member 3 to the left. This cam 96 may be employed either to effect some movement of the sliding member 3 before the action of the camlike projection 10 begins, or it may be employed instead of the latter.

In order to avoid the use of excessive force when cams such as that shown at 9a are employed, the sides 12 and 13 of the clasp bow 2 are made curved and slightly resilient, and the cross-connection 18 which is provided to form the end of the opening 17 is slotted. Thus when the head of the cam 9a engages in the opening 17 the sides 12 and 13 can bend slightly outwards.

It is, of course, clear that modifications may be made in the constructions shown by way of example. Thus a spring such as that shown at 8 ma be employed in the construction shown in igure 1. Obviously also any arrangement of the fixed and movable teet is possible and the number of them is chosen in accordance with the amount of gripping action desired.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 1.
